Our Approach to New Installs

What PDM Roofing Does Differently on Roof Installation Projects in Calamus

New roof installation is where the full system either gets built right or inherits problems that surface during the first heavy rain or the first hard winter. Our process accounts for every layer, every penetration, and every transition -- not just the material that's visible from the street.

📄

Pre-Installation Decking Assessment

On new construction, decking quality and flatness directly affect how the finished roof looks and performs. We assess decking for adequate thickness, fastener schedule compliance, gap spacing, and surface flatness before any underlayment goes down. On additions, we pay particular attention to where new decking meets existing structure, and how the transition will be handled to prevent differential movement issues. A roof that starts on a solid, properly fastened deck is a roof that maintains its integrity through decades of thermal cycling and weather loading.

💧

Underlayment Selection for Local Conditions

Underlayment is the last line of defense between the deck and the weather if the primary roofing material is compromised. We select underlayment based on roof pitch, expected weather exposure, and the specific roofing material being installed. Synthetic underlayments provide better tear resistance, UV resistance during construction delays, and moisture management than traditional felt in most applications, but the right product for a flat-pitch transition section differs from the right product for a steep residential pitch. We explain our selection when we quote so you understand what you're getting and why.

🔧

Flashing at Every Penetration and Transition

Penetrations -- chimneys, skylights, plumbing vents, exhaust fans, valleys -- are where roofing systems develop leaks, often years after installation when sealants age or improper flashings fail. On new construction and additions, we install purpose-designed flashings at every penetration point, using the correct flashing type for the application: step flashing at walls, counter-flashing over step flashing at masonry, pre-formed pipe boots at vent pipes, and formed valley metal at rake intersections. No caulk substitutes, no improvised solutions.

🏭

Ventilation System Integration

A new roof installation is the right time to verify that attic ventilation meets current building standards for the home's attic area. Inadequate ventilation allows heat and moisture to build up in the attic, accelerating shingle degradation, contributing to ice dam formation in cold climates, and creating moisture-related issues in the framing. We evaluate intake and exhaust balance as part of every new installation and make recommendations when ventilation is undersized relative to the attic area we're roofing.

New Construction vs. Re-Roof

What Makes New Roof Installation Different from Replacement

Homeowners who have experience with roof replacements sometimes approach new construction or addition roofing with similar expectations -- and that assumption misses some important differences between the two types of work. Understanding those differences helps you ask better questions during the bidding process and evaluate proposals more accurately.

On a roof replacement, the existing structure provides a known geometry: the dimensions are fixed, the tie-ins are defined, and the primary challenge is matching the old system's characteristics while improving performance and materials. New construction roofing -- whether on a full new build or a home addition -- involves coordination with other trades, adherence to construction sequencing, and in many cases an evolving project scope as the build progresses.

Addition roofing introduces a specific challenge: the transition between the new roof section and the existing home's roofline. Properly executed, this tie-in is watertight and structurally sound. Executed poorly, it becomes the most common leak source on addition projects within the first few years. We plan and detail the tie-in carefully, using appropriate flashing and counterflashing assemblies to create a waterproof joint that functions correctly as both structures age and move.

We work directly with homeowners on custom projects and can coordinate with general contractors and builders on new construction timelines. We communicate clearly about scheduling windows, site access needs, and completion milestones so the roofing phase doesn't hold up other trades -- and so other trades don't inadvertently damage completed roofing work.

Roofing Systems Available

What PDM Roofing Installs for Calamus New Construction

🏠

Architectural Asphalt Shingles

Dimensional laminate shingles remain the most widely specified roofing material for residential new construction in IA, offering a range of profiles, color options, and warranty programs. We specify Class 4 impact-resistant shingles for appropriate applications and can work with architectural requirements for specific profile or color matching. Material selection happens during the specification phase so there are no surprises at the time of installation.

⛩

Standing Seam Metal

For homeowners who want a long-life, low-maintenance new construction roofing system, standing seam metal is the premium option with a 50-plus year expected service life. New construction is actually an ideal time to install a metal system because the structure can be designed for metal from the outset -- including any substrate or framing considerations the specific system requires. We can spec and install metal on new builds and additions of any size.

🌟

Designer and Specialty Profiles

For custom homes, historic renovation work, and projects with specific aesthetic requirements, we install designer shingle profiles, cedar shake-look synthetic systems, composite slate, and natural wood shake where appropriate for the application and local fire codes. Material selection on these projects happens through a collaborative process that accounts for the home's architectural character, HOA or local design requirements, and budget parameters.

🏛

Commercial New Construction Roofing

New commercial construction projects in Calamus including TPO membrane, EPDM, and metal panel systems on low-slope commercial rooflines. We can coordinate with commercial general contractors and operate within standard construction site protocols for schedule, safety, and subcontractor coordination requirements.

🏙

Home Addition Roofing and Tie-In

Full roofing system installation on residential additions -- garages, sunrooms, accessory dwelling units, and whole-home expansions -- including the structural tie-in to the existing roofline. Tie-in work is the most technically demanding part of addition roofing and receives the most detailed attention in our planning and execution process.

📋

Roofing System Specification Consulting

For homeowners in the design phase of a custom build or major addition, we provide roofing system specification input that helps architects and designers select materials, details, and structural requirements that produce an excellent, buildable roofing system. Early roofing input prevents costly specification changes during the construction phase.

Our Process

How PDM Roofing Manages Your Calamus Roof Installation Project

Pre-Install Review and Specification

We review plans, assess the structural framing, confirm material specifications, and develop a detailed scope covering decking, underlayment, flashing design, ventilation, and surface material selection before ordering any materials.

Deck and Substrate Preparation

Decking inspected and any corrections made before underlayment begins. Ice and water shield applied at eaves and all penetration locations. Field underlayment installed and lapped correctly for the roof pitch and exposure.

Flashing, Drip Edge, and Penetrations

All flashing systems installed -- drip edge, step flashing, valley metal, pipe boots, and any custom flashings required by the roof geometry -- before surface material application begins. No exceptions.

Field Installation, Ridge, and Final Inspection

Surface material installed to manufacturer specification, starter course detailed correctly, ridge cap and hip cap installed. Final walk of every plane and penetration before we sign off and release the job.

What Customers Say

New Construction Roofing Feedback from Calamus Clients

★★★★★

"We used PDM Roofing for the roofing on our custom home build. What stood out was their involvement in the specification phase -- they caught a ventilation design issue in the architectural plans before construction started, which saved us a significant amount of money and time compared to correcting it after framing. The installation itself was coordinated well with our general contractor's schedule and the quality of the work is exactly what we hoped for."

A. LundquistCustom Home Owner, IA

★★★★★

"We added a large addition to our home and specifically asked about the tie-in to the existing roof. PDM Roofing walked us through exactly how they were going to handle the transition and what flashing system they were using. After two rainy seasons, there isn't a hint of a leak anywhere -- including at the tie-in. That was the specific thing I was most worried about, and their attention to detail there was exactly what we needed."

M. PhillipsAddition Project, IA

★★★★★

"As a builder in Calamus, I've worked with a lot of roofing subcontractors. PDM Roofing is one of the few who I trust to coordinate on-site without constant supervision. They show up when they say they will, communicate about any field issues they encounter rather than just making a decision without calling, and their quality is consistent across projects. That reliability is what keeps them on my preferred list."

Common Questions

FAQ: Roof Installation in Calamus, IA

When in the construction sequence does roofing happen?+

Roofing installation typically occurs after framing is complete and the roof decking has been fastened, but before most interior trades begin. Getting the structure dried in as quickly as possible -- at minimum with underlayment, even if surface material installation follows later -- protects the framing from moisture exposure during the construction process. We coordinate with general contractors and homeowners to schedule our work at the right point in the sequence, and we can return in multiple phases if the project schedule requires it.

Do I need to select materials before getting a quote?+

No. Many homeowners come to us without having selected specific materials yet, and that is a perfectly reasonable starting point. We can quote the project using standard specification materials and provide alternative pricing for different product selections so you can compare the cost difference between system options. What we do need for an accurate quote is the roof area and configuration, access to plans or the ability to take measurements, and a general sense of the quality tier you're targeting so we quote accordingly.

How is an addition tie-in handled when the existing roof has different-aged materials?+

When a new addition ties into an existing roof, there is often a mismatch between the new and existing roofing materials -- even when using the same product, color matching across different production runs is imperfect, and weathered materials look different from new ones. We plan the tie-in geometry with this in mind, locating the intersection in a position where the visual transition is as natural as possible. In some cases, the addition project is also the right time to address the existing roof if it is approaching the end of its service life -- replacing both at once produces a uniform appearance and eliminates the future disruption of roofing the existing section separately.

What permits are required for new roofing installation in Calamus?+

Permit requirements for roofing vary by municipality and project type. New construction roofing is typically included under the general building permit. Stand-alone new roof installation on an existing structure (a full re-roof) may or may not require a permit in Calamus depending on local building codes. Addition roofing falls under the addition's building permit. We provide guidance on permit requirements for your specific project and work within the inspection process required by your local building department.

Can I be involved in selecting shingle colors or profiles?+

Absolutely. We encourage homeowners to be involved in material selection and provide samples, manufacturer color boards, and project photos to help you visualize options before committing. Shingle color and profile choice affects not just the aesthetic of your home but also the thermal performance, the resale appeal, and in some cases the insurance premium. We build selection consultation into our process rather than simply defaulting to whatever is most convenient to source.
